In this paper we consider a two dimensionalTMD whose electrons and
holes, interacting via a Coulomb-like potential, may give rise to
exciton formation. In order to study the effect of temperature on
the excitonic properties, we use a similar model to the one employed
in Ref. [1]}, where a Frohlich-like Hamiltonian [2]}was
used to characterize the interaction of optical phonons with electrons
and holes in polar crystals. Contrary to Ref. [1]},
where 3D systems were considered, we will focus on excitons on 2D
materials, leading to a difference in the form of the interaction
term [4]}. Moreover, contrary to the aforementioned
work where only the case of \(T=0\)  K was considered, our calculations
cover any temperature value. The Hamiltonian of the considered system
in the center of mass frame of the electron-hole pair reads:
\(\mathcal {H}=H_{0}+H_{1}+H_{2}+H_{3}+H_{4},\)
